Abstract:
Forest ecosystems play an important role in global carbon cycle. Accurate understanding of below- and abovegroundbiomass allocation pattern (i.e. the root-shoot ratio, R/S) and its influencing factors would help to better characterize theregional and global carbon sink, stock and cycle of forest ecosystems. The purpose of this paper was to investigate the effects ofclimatic and stand factors on the root–shoot ratio of China’s natural forests at a large scale. We classified all data of 1109 sampleplots into 17 types of forest and calculated the R/S [root biomass / (stem + branch + leaf biomass)] of the forest communities.Because precipitation could not completely reflect the forest water conditions, the ratio of mean annual precipitation to potentialevaporation was used to evaluate the impact of water availability on the R/S. Finally, latitude, longitude, temperature, wateravailability, stand density and stand age were selected to analyze their effects on the R/S using multiple linear regression.Our results showed the mean value of R/S in China’s natural forests as 0.26. The R/S of deciduous forests was significantlyhigher than that of evergreen forests, and the R/S of broadleaved forests was higher than that of conifer forests. Furthermore,R/S of China’s natural forests was significantly and negatively correlated with the stand age and water availability. The majorinfluencing factors for the R/S of China’s nature forests were latitude and stand density. The results suggested that we shouldinclude in consideration temperature and stand density in calculation of forest carbon stock and forest biomass allocation.
